FINISHING WELT.

Application filed April 16, 1927. Serial No. 184,400.

My present invention relates to finishing resilient material, surmounted by a pair of centrally positioned, contacting independent, parallel beads, the multiple base of the structure being securely stitched or otherwlse fastened together immediately outside of and adjacent the surmounting beads aforesaid to form laterally extending side flanges.

The present invention comprises and includesin addition a concealed or enclosed metallic lining or other bendable stiffening means capable of retaining the welt in deformed position when bent, said lining or means being located at one or both edgesof the structure, the invention having for an object,

among others, to facilitate curvature of the welt without puckering upon either its concave or convex edges, and also to assist in holding the welt down to its seat.

With the foregoing and other objects in view, the present invention will now be par ticularly described and thereafter pointed out by the appended claims.

In the accompanying drawings which form part of this application for Letters Patent, and whereon like characters indicate corresponding parts in the several figures:

Figure 1 is a fragmentary view in perspective of the improved welt showing a transverse section thereof atone end.

Figure 2 isalso a fragmentary view in plan, however, showing the parts illustrated by Figure 1.

Figures 3 and 4iare also fragmentary views in perspective showing modifications of this invention.

Reference being had to the drawings and numerals thereon, 5 indicates the welt base or body oppositely doubled upon itself as at 6, 6, and terminating in loops which, in turn, enclose continuous cords, usually of tightly twisted paper or other suitable material, 7, 7, to form the adjacent contacting and independent surface beads, 8, 8, as shown.

interposed between the base 5 and the enclosed beads aforesaid, is a continuous running strip of flexible material such as 9, affolding additional body material to the completed structure. This filler strip may be of any suitable, material, as also of various forms and arrangements, but the particular form shown has, in practice, proven itself eminently satisfactory and consists of the tint continuous strip of gimp 9, folded upon itself shown at 10, 10, and secured permanently in place by lines of stitches 11, 11,

running from end to end of the welt upon both sides thereof adjacent to the said beads 8 and 8 as shown.

. Within one of the laterally extending side flanges of the welt, outside of the longitudinal stitches 11, as shown by the drawings,

there is provided a metalliclining 12 or other bendable means as aforesaid of relatively stiff but pliable material, preferably enclosed by, and contained within, that edge of the filler-strip 9 before the latter is introduced into the structure. i

In a corresponding location at the opposite edge of the weltstructure, there is provided :a second metallic lining 13, which could also be of like material as that shown at 12, but preferably is formed of a small coil of wire, as best shown by Figures 1, 2 and the modified Figure 3,these linings or inserts 12 and 13 being for purposes that will later appear.

Figures 3. and 4 represent modified forms of the present invention in the former of V which coils of wire 13 and 13 are employed, and in the latter of which two straight wires l2 and 12, as shown,,are employed, and also wirefsubstitutes 14, 14, for the filler cords The foregoing being a description of my invention, its use and operation, briefly stated, are as follows:

In applying this welt to the body, top or other part of automobiles, the beads 8, 8, are forcibly spread apart to admit tacks (not shown) or other fastening means, after which the said beads, under influence of their respective lines of stitches 11, 11, automatically close over the heads of said tacks or fastening means to neatly and effectually conceal the same.

It is to be observed, however, that the particular functions of the metallic lining or other bendable material as aforesaid 12, 13, 12 and 13 come into play when in the 7 or curved surfaces, as indicated by Figure ly and vertically.

2. In practice when such curves are relatively sharp, trimmers have heretofore experienced considerable difliculty in preventing the welt from buckling, both horizontal- By use of the enclosed metallic edge lining or other bendable 1naterialaforesaid, I have discovered that the tendency to buckling of the welt is entirely overcome, the result being perfectly smooth inner and outer surfaces and edges, as shown by Figure 2 of the drawings, and by arranging the stretchable coiled lining on the exterior curved side of greater radius,

this result is facilitated.

It will also be noted that it is within the spirit of my'invention to employ for the purposes indicated a straight wire 12 in one edge and acoiled wire 13 in opposite edge of the welt, as shown by Figures 1 and 2 of the drawings; a straight wire 12 in one edge only; a coiled wire 13 in one edge only; two straight wires or two coiled wires in opposite edges oi the same structure; or, if desired to employ metallic bead-wires 14,14, shown by Figure 4 as a substitute for the bead cords 7, 7, or any bendable stifiening means associated with a side flange of the welt, adapted to retain the welt in deformed positions when bent either horizontally or vertically. In any event, however, in addition to securing per fectly unbroken and smooth curved edges as aforesaid, these metallic or other bendable linings also assist in securing and binding the finishing welt down in its final operative position, and it will be particularly noted that the stiffening means aforesaid as and for the purposes specified,-is equally applicable to all forms of finishing welt having a laterally extending side flange or flanges. I

Having thus described my present invention, what I now claim and desire to secure by Letters Patent is:

.1. In a trimming welt the combination with a relatively thick body portion having a longitudinal slot therein for blind nailing, of a comparatively thin laterally extending side flange on said body portion, and a mewith a relatively thick body portion having a longitudinal slot therein for blind nailing, oi? comparatively thin laterally extending side flanges on said body portion, and

a metallic insert comprising a continuous coil of wire in one of said flanges.

-l. In a trimming welt the combination with a relatively thick body portion having a longitudinal slot therein for blind nailing, ol? comparatively thin laterally extending side flanges on said body portion, and a continuous flexible metallic element embedded in one of said flanges.

In a triinniing welt the combination with a relatively thick body portion having a longitudinal slot therein for blind nailing, of comparatively thin flanges extending laterally from said body portion, and a bendable insert extending longitudinally in one of said flanges, adapted to retain the welt in deformed positions when bent.

6. In a trinnning welt the combination with a relatively thick body portion having a longitudinal surface slot therein for blind nailing, o't' coin 'iaratively thin flanges OX- tending laterally from said body portion, and bendable inserts positioned longitudinally in each of said flanges, adapted to retain the welt in deformed positions when bent.

T. In a trimming welt the combination with a relatively thick body portion having a longitudinal slot therein for blind nailing, of a comparatively thin laterally extending side flange on said body portion. and bendable stifi'ening means associated with said flange adapted to retain the welt in deformed positions when bent.

in testimony whereof I allix my signature.
